AYLOR AND JOHN O. DIAS, OF VILMERDING, PENNSYLVANIA,

ASSIGNORS OF ONE-TENTH TO JOSEPH REDFERN, OF SAME PLACE.

COKE-OVEN.

SPECIFICATION forming part of Letters PatentvNo. 561,922, dated June 9,1896.

Application liled January 2, 1896. Serial No. 574,133. (No model.)

To all whom zt may concern.-

Be it known that we, NORTON B. TAYLOR and JOHN O. DIAS, citizens of theUnited States, residing at W'ilmerding, in the county of Allegheny,State of Pennsylvania, have invented certain new and useful Improvementsin Coke-Ovens, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements incoking-ovens of that class in which the bottom or platform is designedto be moved vertically; and it has for its object, among others, toprovide (n improved apparatus of this character which shall be simpleand cheap in its construction, durable and efficient in its operation,and having provision for scraping the coke off of the bottoni when it islowered sufficiently to clear it, after which the same is drawn outandthe coke allowed to fall into a chute arranged be neath the oven.Suitable means are provided for causing the rise and fall of the bottom.The bottom is mounted on a truck and means are provided for moving thetruck out after the bottom has been lowered and after the coke has beendischarged; for moving it back again into position and the ovenrecharged, and the operation repeated.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thespecification, and in which* Figure 1 is a vertical section through theoven with the truck and other parts shown in elevation, and Fig. 2 is atop plan of the truck and the raising and .lowering means with thebottom removed.

Like letters of reference indicate like parts in both the views.

Referring now to the details of the drawings by letter, A designates theoven, and A a cast-iron ring built therein, as shown, the inner face ofthe ring being preferably lightly beveled, as seen in Fig. l, and.beneath said ring the brickwork of the oven is offset, as shown at ce,so that a shoulder a' is formed by the inner end face of the ring,serving as a stop for the upward movement of the movable bottom, as seenin Fig. l.

The bottom, which is carried by the truck, comprises the castiron orother suitable plate B, the vertical walls of which are formed with thegroove or recess b, as seen in Fig. l, into which is forced or held themineral wool, asbestos, or some suitable non-conducting substance B,upon which are the bricks or tile B2, constituting the upper face of thesaid bottom, and which tile or brick have their outer edges beveled, asseen at h2, and are anchored to the inner upper flange b' of themetallic plate B, as seen in Fig.- l, the said beveled edgescorresponding to the bevel or taper of the inner face of the cast-ironring A' and the adjacent wall of the oven, all as clearly illus tratedin Fig. l.

Depending from the under side of the plate B, and secured thereto in anysuitable mauner, are the screws O, there beingfive shown, althoughthisnumber may be varied as may be required, and on these screws aremounted for movement the worm-gears D, with which are mounted to engagethe Worms E, carried by the shafts E', mounted in suitable bearings inor upon the truck F, mounted upon Wheels F', carried by the shafts oraxles f 8o and adapted to travel upon the tracks G, suitably supported,as upon I-beams or other equivalents G', extending across the pitbeneath the oven, and beneath which is designed to be arranged a chute,designated in this instance by the inclined dotted line H in Fig. l. Theend of the truck is provided with a hook or other analogous means FA2for the attachment or connection of a chain orother means, (not shown,)whereby the truc-l: may be withdrawn when desired.

The shafts E are extended at the front end and carry each a bevel-pinionI, which pinions are adapted to mesh With similar bevelpinions .l on theshaft J, mounted in suitable bearings j on the front end of the truckand adapted to be revolved through the means of a sprocket-wheel K ousaid shaft, and a sprocket-chain K, passed around the Asame and adaptedto be driven from any suitable source of power. (Not shown.)

The asbestos or mineral wool serres to re- IOO tain all possible heatand at the same time prevent warping of the plate.

Vith the parts constructed and arranged substantially as above describedthe operation is as follows: lVith the parts in the position in whichthey are shown in Fig. l, and the 'coke ready to be withdrawn from theoven, the oven having been charged and the coke burned in the usual way,the bottom is lowered by means of the screws and the wormgears driven bythe sprocket chain and wheels, and as the bottom is brought so that itsupper face is just below the lower face of the cast-iron ring A thetruck is drawn out, and as it is drawn the cast-iron ring scrapes thecoke off of the bottom and the said coke falls down to the rear of thetruck and between the rails into the pit or onto the chute when thelatter is employed, and as soon as the coke has all been discharged thetruck is run back into position again and then raised through the mediumof the bevel-pinions, worms, and worm-gear and the shoulders a', and,engaging the end face of the ring A,serve as stops and limit the upwardmovement of the bottom. The sprocket chain and wheel may be movedoutward with the truck, or the chain may be removed from the sprocketwhen the truck is drawn outward and pushed back, or there maybe aseparable connection between the shaft carrying the sprocketwheel andthe shaft J', so as to be readily separated and driven oravoid carryingof the sprocket wheel and chain with the truck in its movement.

Modifications in detail may be resorted to without departing from thespirit of our invention or sacriicing any of its advantages.

Having thus described our invention, what we claim as new, andvdesire tosecure by Letters Patent, is-

- 1. A coke-oven provided with a verticallymovable bottom, comprisingthe metallic plate and non-combustible layer adjacent to the plate, theupper edges of the plate being iianged and extended inward over thenoncombustible layer, and brick or tiling resting upon said layer andanchored to the plate, combined with a combined stop and scraper forsaid bottom; substantially as described.

2. A coke-oven provided with a verticallymovable bottom, comprising ametallic plate and non-combustible layer adjacent to the plate, theupper edges of the plate being flanged and extended inward over thenoncombustible layer,brick or tiling resting upon said layer, andanchored to the plate, the outer edges of which are beveled, and thebrick above the same being correspondingly beveled, combined with acombined stop and scraper for said bottom, the inner edge of which isalso beveled; substantially as described.

3. A coke-oven provided with a verticallymovable bottom, comprising ametallic plate and non-combustible layer adjacent to the plate, theupper edges of the plate being iianged and extended inward over thenoncombustible layer, brick or tiling resting upon said layer, andanchored to the plate, the.

outer edges of which are beveled, and the brick above the same beingcorrespondingly beveled, combined with a combined stop and scraper forsaid bottom, the inner edge of which is also beveled, and a truck onwhich said bottom is mounted, and means for moving said truckhorizontally after the bottom is lowered to cause it to be engaged bysaid scraper; substantially as described.

4. The combination with a vertically-movable bottom to a coke-oven, ofthe oven, and a metallic ring forming a stop for the upward movement ofthe bottom, and serving as a scraper when the bottom is lowered andmoved outward; substantially as described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
